r289932 accidentally broke the rule skip calculation. The address family
argument to PF_ANEQ() is now important, and because it was set to 0 the macro
always evaluated to false.
This resulted in incorrect skip values, which in turn broke the rule
evaluations.
"rmii", use rmii mode for the MAC, otherwise use MII mode. The code is
somewhat duplicated between these drivers for this.
Also, add AT91RM9200 compatibility strings to the ate driver. In the
future, there's a good chance that ate will lose the MACB support and
only attach to the AT91RM9200 EMAC device since the macb works now
that RMII support has been added to it.
driver. This is taken from the MAC at boot, but can be overridden with
'options AT91_MACB_USE_RMII'.
Switch to macb for HL201 and SAM9G20EK boards. It now works both
places. Also start to sneak up on FDT for the SAM9G20EK board, but
leave disabled due to issues with MMC that haven't been resolved.
Add early debug support for the SAM9G20EK since that is required
for FDT to work presently on these SoC.
Use the right intmax_t type instead of intptr_t in a few remaining
places.
Add support for CTLFLAG_TUN for the new fixed with types. Bruce will be
upset that the new handlers silently truncate tuned quad-sized inputs,
but so do all of the existing handlers.
Add the new types to debug_dump_node, for whatever use that is.
Bump FreeBSD_version again, for good measure. We are changing
SYSCTL_HANDLER_ARGS and a member of struct sysctl_oid to intmax_t.
Correct the sysctl typed NULL values for the fixed-width types. (Hat

Things seem to get stuck in low memory conditions where no bufs are available,
the reclamation path is called to wakeup the daemon, but no sleeping is done.
Because of this, we are stuck in a tight loop in the current process and
never run said reclamation path.
This was introduced in r289279 . This is only a temporary workaround
to restore system usefulness until the more permanent solutions can be
found.
Tested:
* Carambola2, 64MB (and 32MB by manual config.)
Add S8, S16, S32, and U32 types; add SYSCTL*() macros for them, as well
as for the existing 64-bit types. (While SYSCTL*QUAD and UQUAD macros
already exist, they do not take the same sort of 'val' parameter that
the other macros do.)
Clean up the documented "types" in the sysctl.9 document. (These are
macros and thus not real types, but the manual page documents intent.)
The sysctl_add_oid(9) arg2 has been bumped from intptr_t to intmax_t to
accommodate 64-bit types on 32-bit pointer architectures.
This is just the kernel support piece; the userspace sysctl(1) support
will follow in a later patch.

This is required for fragments and encapsulated data (eg tunneling) to be redistributed
to the RSS bucket based on the eventual IPv6 header and protocol (TCP, UDP, etc) header.
* Add an mbuf tag with the state of IPv6 options parsing before the frame is queued
into the direct dispatch handler;
* Continue processing and complete the frame reception in the correct RSS bucket /
netisr context.
Testing results are in the phabricator review.

On the mpc85xx SoC family, writes to any part of a word in the CCSR affect the
full word. This prevents single-byte writes from taking the desired effect.
Code copied directly from ARM.
This speeds up buildworld by 16% on my system and buildkernel by 35%.
Rather than calling mkdep(1), which is just a wrapper around 'cc -E',
use the modern -MD -MT -MF flags to gather and generate dependencies during
compilation. This flag was introduced in GCC "a long time ago", in GCC 3.0,
and is also supported by Clang. (It appears that ICC also supports this but I
do not have access to test it). This avoids running the preprocessor *twice*
for every build, in both 'make depend' and 'make all'. This is especially
noticeable when using ccache since it does not cache preprocessor results from
mkdep(1) / 'cc -E', but still speeds up compilation with the -MD flags.
For 'make depend' a tree-walk is still done to ensure that all DPSRCS
are generated when expected, and that beforedepend/afterdepend and
_EXTRADEPEND are all still respected. In time this may change but for now
I've been conservative. The time for a tree-walk with -j combined with
SUBDIR_PARALLEL is not significant. For example, it takes about 9 seconds
with -j15 to walk all of src/ for 'make depend' now on my system.
A .depend file is still generated with the various rules that apply to
the final target, or custom rules. Otherwise there are now
per-built-object-file .depend files, such as .depend.filename.o. These
are included directly by make rather than populating .depend with a loop
and .depend lines, which only added overhead to the now almost-NOP 'make
depend' phase.
Before this I experimented with having mkdep(1) called in parallel per-file.
While this improved the kernel and lib/libc 'make depend' phase, it resulted
in slower build times overall.
The -M flags are removed from CFLAGS when linking since they have no effect.
Enabling this by default, for src or out-of-src, can be done once more testing
has been done, such as a ports exp-run, and with more compilers.
The system I used for testing was:
